Links are being triggered periodically and put to sleep in case it was not possible to establish them
within a certain amount of time. Hence it might happen that permanent links will be dialed in background
and replace links with lower priority again as soon as they got established. In case of interfering links
sharing the same resources (for instance in dual-SIM operation) you may define a switch-back interval
after which an active hotlink is forced to go down in order to let the higher-prio link getting dialed again.
Bridge interface: If WAN is configured as WLAN client, the LAN interface to which the WAN
link should be bridged.
Outgoing traffic can also be distributed over multiple links on a per IP session basis. Choose the option
"distributed" as an Operation Mode with the appropriate Weight.
In the following example, the outgoing traffic will be distributed between LAN2 (80 %) and WWAN1
(20 %) links.
Note
This option is general and applies to all outgoing traffic. See Section 7.3.3, “Multipath Routes”
for more detailed configuration.
We recommend using the permanent option for WAN links. However, in case of time-limited mobile
tariffs, the switchover option should be used.
After clicking on the WWAN "Edit" button, you can additionally set the "IP passthrough" option for the
selected LAN interface. The result is that the connected device over the selected LAN port will obtain
M!DGE's mobile IP address via DHCP. In another words, M!DGE will be transparent for the connected
device and will only serve for the mobile connectivity. Typically, such connected device (e.g. firewall)
will not need any special configuration facing M!DGE, it will just use its mobile IP address (usually the
public IP address).
